The steam power plant in the figure works on the ideal Rankine cycle with the state data shown. The net electrical output is 60 MW (take generator losses as zero). Determine (a) the net work per kg of steam, including the pump work found from v_{1}ΔP (answer in kJ/kg), (b) the thermal efficiency of the cycle (answer in %) and (c) the mass flow rate of steam required (answer in kg/s).
